Solgar Grape Seed Extract 100 mg is a source of polyphenols and OPC. Oligomeric proanthocyanidins (OPCs) are flavonols of plant origin found in grape seeds (or pine bark). Oligomeric proanthocyanidins, as a group of differentiated compounds, receive their name from the flavonoids from which they are obtained. This class of compounds are found in very high concentrations in the skin and seeds of different plant species. The simplicity of their chemical structure differentiates these versatile compounds from the more complex flavonoids from which they are partially derived. This simple chemical structure is what allows its rapid absorption into the blood. Much of the research on TPOs has been done with grape seeds. Grape seed extracts are marketed with polyphenol concentrations of up to 80%. They are rich in different type B proanthocyanidins, which are not found in pine bark extracts, and in polyphenols found in red wine (grape skin), peanuts and some plants.
